Skin care melanoma
Melanoma is less common, but more dangerous. Melanoma is the most dangerous form of skin cancer, caused by sunburn during our early years. Each year in Australia, nearly 10,000 new cases are diagnosed, with 1,200 people dying from this disease every year. Melanoma skin cancer remains the most dangerous subtype because of the risk of spread. About 1,800 people die from melanoma skin cancer annually in the UK.
Melanoma is more likely than nonmelanoma skin cancer to spread to lymph nodes and other parts of the body. Melanoma is also one of the most frequently occurring cancers in Australia. Men have a 1 in 26 chance, and women a 1 in 36 chance, of developing a melanoma before they are 75. Melanomas vary greatly in appearance. Some melanomas may show all of the ABCD characteristics, while other may only show changes in one or two characteristics.
Moles that are present at birth and atypical moles, have a greater chance of becoming malignant. Recognizing changes in your child’s moles, by following this ABCD Chart, is crucial in detecting malignant melanoma at its earliest stage. Moles are very common and normally change only slightly over time; however in melanoma there may be a more rapid increase in size – symptoms include a darker or variable discoloration, itching, and possibly ulceration and bleeding.
Sunscreen may be used on babies over six months. Sunscreen users should buy one with a sun protection factor (SPF) of at least 15. Be sure to put on enough lotion. Sunscreens are rated in strength according to a sun protection factor (SPF), which ranges from 2 to 30 or higher. Those rated 15 to 30 block most of the sun’s harmful rays.
Sunscreens are rated by an SPF (sun protective factor) number, which is a multiplier of your skin’s exposure time before burning. For example, an SPF of 4 means you can stay in the sun four times longer before burning than if you were wearing no sunscreen.
Tanning booths use ultraviolet rays. Makers of the booths may claim that they use “harmless” UVA rays. Tanning occurs when the sun’s ultraviolet (UV) rays penetrate the skin’s inner layer, causing the skin to produce more melanin, or dark pigments, in response to the sun’s damage.
Squamous cell cancers have a somewhat greater (although still quite small) risk of spreading, so staging may sometimes be done, particularly in people who have a high risk of spread. This includes people with suppressed immune systems, such as those who have had organ transplants and people infected with HIV, the virus that causes AIDS. Squamous cell carcinomas enlarge slowly and steadily and can invade neighboring tissue, like the eye. They can also spread to distant parts of the body (metastasize) if not treated early.
Sunlight is a major source of this UV radiation, but it may also come from artificial sources like tanning booths. The strength of the light and the length of the exposure determine just how much exposure to UV rays you might have had. Sunlight is most intense at midday, so try to limit exposure during these hours. Use high-quality sunscreens, preferably with SPF (sun protection factor) ratings of at least 30.
Non-melanoma skin cancer (NMSC) is the most common cancer diagnosed in Australia, with around 400,000 new cases per year. However, data on incidence and prevalence are not routinely collected. Non-melanoma skin cancers include basal cell carcinoma and squamous cell carcinoma. It is a good idea to talk to your doctor about your level of risk and for advice on early detection.
